      Description

      Implement windowed aggregate (the Window relational expression) in the interpreter.

      Aggregate functions could be implemented by generating Java ASTs (via AggImplementor) but it would be simpler to implement them using AggregateFunctionImpl, as if they were user-defined aggregates. (AggregateNode already does this.)
